Neutron Emission Spectroscopy (NES) can be used to study the fuel ion populations in fusion plasmas as has previously been demonstrated at JET in DT experiments. During the spring of 2006, the 2.5MeV time-of-flight spectrometer TOFOR, designed to work at Optimized Rate (OR), was installed at JET. High count-rate is an essential figure of merit for NES since the statistical accuracy sets the limit for the information that can be extracted from the data. TOFOR records neutrons from d + d Æ 3He + n reactions in a time-of-flight (tTOF) spectrum, centered at 65ns corresponding to En = 2.45MeV, with a shape determined by the motional state of the fusing deuterons and refs. there in. The net result is a spectrum that is particularly sensitive to high velocity ions giving rise to distinct signatures such as tails extending up to En = 7MeV.
